Lauren Bacall was born in 1922. She began her career as a model before turning to acting.
Humphrey Bogart was born 1899 on Christmas Day. His father was a surgeon and his mother an illustrator and suffragette. He was sent to private schools but didn't do well and was finally expelled. He joined the navy at the end of WWI and after a stint there began jobs in the theatre, taking on small roles. When the Depression came, theatre was hit badly so he did what many other actors did and headed to Hollywood. He became a close friend and drinking buddy of Spencer Tracy and the friendship lasted till Bogie's death.
Bogie and Bacall met while filming To Have and Have Not in 1944. She was 19; he was 44. The chemistry was immediate. At this time Bogie was married to his third wife, Mayo Methot. It was a problematic marriage. She was also a hard drinker and jealous to boot with a fiery temper. She set fire to their house once, stabbed her husband and on more than one occasion slashed her wrists in a suicide attempt. Bogie once said, "I wouldn't give two cents for a dame without a temper." but in this case it might have been a little too much of a good thing.
Director Howard Hawks had become Bacall's mentor and was not pleased with the growing relationship between the two stars. He did what he could to stop it but he might as well have tried to halt a runaway locomotive. He expressed his take on their affair, "Bogie fell in love with the character she played so she had to keep playing it the rest of her life."
Bogie and Bacall kept their meetings discreet in the beginning bridged by steamy love letters. He filed for divorce early in 1945 and later that year they were married in a quiet ceremony.
They remained married till his death in 1957 from esophageal cancer. They had two children, a son and a daughter. They went on to make three more movies together, a winning combination on screen, as in life. They were each stars in their own right but together, they were unmatched.
When he died, a small whistle from Bacall's charm bracelet was buried with him, with the inscription reading, "If you want anything, just whistle," a reference to the words Bacall spoke in their first movie together, "You know how to whistle, don't you Steve? You just put your lips together and blow."
